INDIRECT DRIVE
In this drive mode:
PT1:
See below.
PT2:
Selects relay operating mode:
In
→
monostable
Out
→
bistable
PT3:
Not used.
In this drive mode, the special services decoder unit’s relay is
actuated at the same time that another event occurs. The table below
summarizes possible cases and the required position for jumper PT1
(in = Specifi c, out = Generic).
Take, for example, the sixth line of the table. In this case, the decoder
unit relay will be actuated, e.g., in order to turn on the stair lights,
whenever the door lock release key at a “generic” apartment station is
pressed following a call. In the case contemplated in the fi fth line, on
the other hand, the relay will be actuated ONLY when the door lock
release key is pressed at the specifi c apartment station identifi ed by
code “NNNN”, and not when the key is pressed at other apartment
stations.
SPECIAL SERVICES DECODER UNIT
APPLICATION DIAGRAMS
A) ACTUATING SPECIAL SERVICES VIA A MOMENTARY
TRIGGER ACTION
(Turning on stair lights, opening electric gates, etc.)
Description:
This application is used in cases were momentary closing of a
contact is suffi cient to actuate a given service.
In a timer-controlled stair lighting system, for instance, the special
services decoder unit contact can be connected in parallel with a
pushbutton in order to turn on the lights when a code is entered at
the keypad of any entrance module or the guard door switchboard
station.
The special services decoder unit operates with two codes. In this
case, then, the lights can be turned on by entering either the fi rst
code or the second (lights will be turned off by the timer).
Connection:
Jumper settings and programming:
Program the 2 special service codes, carefully following the
instructions provided in the section headed “Programming - Direct
Drive”, steps 1, 2 and 3.
Thus, when one of the two codes (preceded by a zero) is entered
via the entrance panel or switchboard station keypad and the
call button
is pressed to transmit the code, the relay will be
energized for approximately 300 ms, switching the pole contacts
and actuating the associated service.
The display will show the word “OFF” and the entrance module will
generate an audible signal consisting of one short tone and one
long tone. This signal will be repeated three times.

B) ACTUATING SPECIAL SERVICES VIA A MOMENTARY
TRIGGER ACTION WITH ACTUATION FEEDBACK
(Turning on stair lights, opening electric gates, etc.)
Description:
This application is similar to the one described above, except that
a feedback signal confi rming that the service has been actuated
is received at the device (i.e., the entrance module or guard door
switchboard station) where the special service code was entered.
For example, an electric driveway gate can be opened by entering
the special service code on the keypad of the entrance module
near the driveway, where the display will show the word “ON” to
